WSW STD Screening

STD Screening in Women having Sex with Women (WSW)

Women who have sex with women can contract sexually transmitted diseases from the transfer of the cervical or vaginal fluid, direct contact with mucosal or through the use of unwashed sex toys.

Sexually transmitted diseases among WSW include Bacterial vaginosis, Trichomonas Vaginalis, Genital Herpes, Genital warts, HPV infection, Syphilis, HIV, Hepatitis A, B &C, gonorrhoea and Chlamydia.
They should undergo screening tests like:

1.Full vaginal and cervical smear and culture tests to exclude the sexually transmitted diseases mentioned above.
2.Blood tests to screen for Syphilis, Herpes Simplex Virus and HIV.
3.Regular PAP smears

Vaccination against Hepatitis A &B is a good way to prevent transmission of the diseases. Safe sexual practices also reduce contraction of such diseases.

1.History of discharge: When does it start and how long has it been? As for the discharge, what is the color, odor and which site (vagina, penile area, pharynx, rectum and eye) does it involve? Has the patient has similar episodes before and what’s the diagnosis then? Are there other systemic symptoms such as fever, eye symptoms and joint pain?

2.Sexual History: This is important especially to determine if the genital discharge is due to sexually transmitted diseases. It is important to enquire about the patient’s sexual orientation, number of partners involved, whether they engage in commercial sex workers also venue for meeting partners. Enquiries on whether their partners have any symptoms or signs as well as if their partners have any sexually transmitted disease are important history.
